top
up
reverse
fix
Answer is Right!
Answer is Wrong!
The correct answer is: A. top
The top property specifies the top offset of a positioned element. It is a length value that specifies the distance between the top edge of the element and the top edge of its containing block.
The up property is not a valid CSS property.
The reverse property is a valid CSS property, but it does not specify the top offset of an element. It specifies the direction in which an element scrolls.
The fix property is not a valid CSS property.
